10 Everyday Things You Didn’t Know The Purpose Of

10 Everyday Things You Didn’t Know The Purpose Of 10 Earbuds In October 2016, tech giant Apple released their latest device: The Apple AirPods Despite sounding like a futuristic flying machine, the AirPod is a wireless in-ear headphone that can remotely play music from any connected iPhone

While the biggest mystery about the AirPod might be why anyone would pay $200 for earphones, another intriguing feature has captured people’s interest Like Apple’s EarBuds before them, the AirPod has three seemingly unnecessary extra holes in its casing These holes aren’t extra speakers, as some have suspected, but something far smarter The holes exist to let air into the headphones You see, to ensure earphones don’t fall out, they have to create a seal in our ear canal

But speakers need air to vibrate sound waves through Having the holes allows a free flow of air while the AirPod remains nestled in your ear, creating a better sound and allowing the device to hit deeper bass notes 9 Wine bottle Anyone who enjoys a drink or two will have noticed that wine bottles have an indentation Called a “punt”, almost all wine bottles have this concave dome curving into the bottom And champagne bottles have even deeper ones

As tends to happen when you mix mystery with copious amounts of booze, many pet theories and old wives tales have cropped up to explain this curious design feature Some conspiracy theorists even claim it’s a grand conspiracy for the wine industry to rip you out of extra wine, making the bottle look bigger than it really needs to be The reality is much simpler Wine bottles need to be able to withstand the pressure of having a liquid inside, and the curved surface creates a much stronger structure That’s why champagne punts are much deeper than wine ones, the pressure is much higher

And no-one wants their bottle of fizz to explode mid-celebration 8 Cylinder wire You may not have heard of the ferrite core But you likely use this under-appreciated piece of technology every day If you’ve ever wondered what that weird lump on your charger cable is, it’s a ferrite core This little plastic-coated cylinder is actually a chunk of magnetic iron oxide, and can be found on almost all chargers and other electronic cables

Its job? To prevent interference between your electronics You see, most electronic devices communicate using radio waves And attaching a cable to one has the same impact as an antenna, amplifying the signal of a device to a level where it can interfere with other electronics The ferrite bead, or ferrite choke, blocks the transmission of these radio waves, preventing your device’s signal from becoming too powerful Without a ferrite bead, plugging in any electronic could mess with the signal of other devices and cause them to fail

7 Hole in the top of pen lids It won’t be a surprise to you that more people than ever are using keyboards, mostly to write tweets that no-one will ever read But more than 34 billion ball-point pens were imported into the US last year alone, clearly plenty of people still like to write by hand Those of you who do may have noticed that most biros, including the market-leading Bics, tend to have a mysterious hole in their lid Most people think the hole is there to stop the pen drying out

But the real, rather admirable, reason some many biros come with a hole in the air is to save lives The idea is that if someone is swallows the pen lid, the hole will allow the through-flow of air, preventing that person from choking At present, over 100 Americans a year die from choking on pen lids And without Bic’s iconic hole, that figure could be much higher 6 Bobble Hats If you had to guess an item of clothing with a long military history, you probably wouldn’t pick the bobble hat

Nowadays these bumpy beanies are mostly a neat fashion accessory to go with your unicycle and your handlebar mustache But before the hipsters got hold of them, bobble hats were seriously useful to the French military Under the reign of Napoleon in the 19th Century, all French infantryman had a pom-pom sewn onto their hats Different colors denoted the different regiments, and served as a quick way to identify and organize troops The French military abandoned the bobbles before the 20th Century, presumably deciding that walking around a battlefield with a bright red bobble on your head is like painting a target on your forehead

But the French navy found that the small lump worked a bit like an antenna, warning them if they were about to hit their head on a ship’s beam or submarine roof They still wear them to this day 5 Chinese Takeaway Box The famous white takeaway box was invented by Chicagoan Fredericks Weeks Wilcox in 1894, and has been made iconic by decades of appearances in movies and TV But it’s always been kind of awkward to eat from It’s too tall to easily pick all of the food out and too boxy to comfortably pour onto a plate

Well, it turns out the takeaway box hasn’t been badly designed We’ve just been overlooking its hidden feature The takeaway box is designed so that if you unfold the wall, the box spreads out into a paper plate This makes it far easier to get to all that delicious food, and has the added benefit of being a disposable surface to eat it on And if you can’t finish all that food at once, just fold the box back up and set it aside for later

4 Pockets on jeans Jeans were first invented all the way back in 1873 by Jacob W Davis and the Levi Strauss Company Since then, jeans have gone through a near infinity of different designs, styles and fashions You can buy them skinny or loose, ripped or pristine, blue, red, green, or, if you want people to hate you, yellow But, despite all the changes, two things that have remained over the years are the tiny interior pocket and the seemingly useless buttons

They may seem out of place now, but both those features once had very important uses The small pocket was designed to be the perfect size to fit a pocket-watch in And the buttons were there to reinforce and strengthen the trouser seams You see, jeans were originally meant for manual laborers, who needed their trousers to be strong enough to withstand wear and tear 3 Dials under traffic lights Those of you who live in the UK might have noticed these small dials at pedestrian crossings

Hidden away under the wait button’s box, these miniscule plastic coils may seem out of place But they actually serve a vital function, helping blind people cross the road Designed in the 1980s by a team from the University of Nottingham, the cones spin when the crossing light turns green That means that when a blind or visually impaired person reaches the road, they just have to put their hand on the device and wait for it to spin Though they aren’t mandatory for councils to install, the innovation has proven popular

The first spinning cone was installed in 1989 By 1995, 10,000 models were already in use at crossings up and down the country 2 Lollipop holes You probably wouldn’t think that there’s much mystery to a lollipop You just stick it in your mouth and enjoy the taste as the sugar goes rushing off to melt your teeth and give you diabetes But there is one thing that’s perplexed connoisseurs of candy for years, why do Chupa Chups lollies have a hole in the stick? The explanation behind the hole can be found in the manufacturing process

You see, the lollipop brands noticed that there was nothing substantial holding their candy in place In other words, as soon as the lolly part melted slightly, it was likely to slide down the stick and fall off By designing in a hole, the manufacturers were able to ensure that some of the lolly would set into the stick during the factory process, anchoring it in place and preventing it from flying off in the sun 1 iPhone hole We’ve already solved the mystery of the EarBud’s holes But there’s another famous Apple product with a part that has left users mystified

On the back of most iPhones, users will find a small pinhole between the rear camera and the light The hole was introduced in 2013 with the iPhone 5S, and has featured on every iPhone released since So what is it? A ventilation hole? A motion sensor? A hidden portal to the netherworld? Actually, it’s much simpler than that The hole is just a microphone, one that switches on when you film using the back camera Having an additional microphone on the back of the iPhone allows for a better sound when you’re trying to film something in front of you

Plus it means Siri can hear you even when you aren’t using your iPhone, allowing you to ask it questions from further away Although, we’re still not entirely convinced it isn’t also a portal to the netherworld So, that was 10 Everyday Things You Didn’t Know The Purpose Of Which object’s hidden powers surprised you the most?
